IEI, owned by the American telecom giant IDT Corp, anticipates starting commercial production by 2020, producing 50,000 barrels a day initially. While that figure is a fraction of the 270,000 barrels per day Israel currently consumes, Vinegar maintains it is a further key step toward achieving energy independence. Vinegar proposes thermal recovery for Israeli shale oil.

The Tamar natural gas discovery will supply the Israeli domestic market for decades. Currently appraised at 8.4 trillion cubic feet (Tcf) Tamar is expected to deliver its first sales in 2013.

Lying to the north-west of Tamar, Leviathan holds around a further 16 Tcf, almost all of which could be slated purely for export. According to businessman Yitzhak Tshuva, part owner of Leviathan, its gas too will be ready for production by 2013, well ahead of schedule. But even at a combined total of 25 Tcf, Tamar and Leviathan only represent around a fifth of the 122 Tcf the US Geological Survey estimates lies in the Levantine Basin, much of which falls within Israeli jurisdiction.
